More Information
Summary:A differential load detection apparatus and method are provided for detecting a wireless power receiver in a wireless power network. The differential load detection method includes transmitting first detection power for detecting the wireless power receiver, transmitting second detection power when an impedance variation greater than a first predetermined threshold value and equal to or less than a second threshold value is detected, and waiting for a reception of an advertisement signal according to the transmission of the second detection power from the wireless power receiver.
